Questions about this pairing

Which panel is better: Boviet Solar BVM7612M-580-H-HC-BF or Boviet Solar BVM7612M-545-H-HC-BF?
According to our database: Boviet Solar BVM7612M-580-H-HC-BF has higher module efficiency (22.45% vs 20.90%); Boviet Solar BVM7612M-580-H-HC-BF tolerates heat better (temp coeff -0.300%/°C vs -0.350%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Boviet Solar BVM7612M-580-H-HC-BF and Boviet Solar BVM7612M-545-H-HC-BF?
Boviet Solar BVM7612M-580-H-HC-BF has a module efficiency of 22.45%, while Boviet Solar BVM7612M-545-H-HC-BF is 20.90%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Boviet Solar BVM7612M-580-H-HC-BF use vs Boviet Solar BVM7612M-545-H-HC-BF?
Boviet Solar BVM7612M-580-H-HC-BF uses TOPCon cells; Boviet Solar BVM7612M-545-H-HC-BF uses PERC. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.
What is the warranty on Boviet Solar BVM7612M-580-H-HC-BF and Boviet Solar BVM7612M-545-H-HC-BF?
Boviet Solar BVM7612M-580-H-HC-BF has a 30 years power warranty; Boviet Solar BVM7612M-545-H-HC-BF has a 30 years power warranty. The power warranty guarantees a minimum percentage of rated output at the end of the warranty period (typically 80-87%). Product (materials) warranties are usually shorter.
Are Boviet Solar BVM7612M-580-H-HC-BF and Boviet Solar BVM7612M-545-H-HC-BF bifacial panels?
Both Boviet Solar BVM7612M-580-H-HC-BF and Boviet Solar BVM7612M-545-H-HC-BF are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.

Every figure here is from the manufacturers' own datasheets - a dash means the value is not published, never an estimate. The thirty-year projection and the temperature scenarios are calculations from those figures, and each states its assumption above.
